GAR-DOOR LOCK.

SPECIFICATION forming part of Letters Patent No. 288,988, dated November 27, 1883. application filed March 14, 1883. tlllodcl.)

['0 aZZ whom it may concern:

Be it known that I, J osnrn HYDE Frsnnn, of Deerfield, in the county of Lake and State of Illinois, have invented new and useful Inr provenients in Gar-Door Locks, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which Figure Iis a broken elevation of the inside of a car and car-door provided with my lock attachment; Fig. II, a View of Fig. I, looking in the direction of dart 6; Fig. III, a view of Fig. IV, looking in the direction indicated by the dart c. Fig. IV represents the jamb-face of the door-post, the same as at Fig. II, eXceptthe section of the door is omitted and the look bolt thrown back, as where the door is to be opened, Fig. II representing the door closed. Fig. V is a view of the lock-plate detached from the other parts, looking at it inthe same direction as at Fig. I.

The present invention relates to locking sliding doors to freight-cars from the inside.

The nature of the invention consists of a pivoted bolt,which is held locked or unlocked by a gravity-catch, as hereinafter shown and described.

T represents a portion of the inside of a car, A the door-post, and G a port-ion of the sliding cardoor.

E L represent the lock or bolt-plate, which is attached to the inner face of the door-post A by means of screws put through the plate E in the ordinary manner. The bolt J is pivoted to the plate E L at Z, and the wood of the post A is cut away, as represented by dotted lines S S, Fig. II, that the bolt may occupy the position shown at Fig. II, and lock the door G, or theposition shown at Fig. 1T,where the door is to slide. Theshank O of the bolt terminates in a D-shaped ring, that the bolt J may be held in the positions shown. At Figs. I and II the bolt J is represented as thrown out from the plate E, and the ring thrown down, and held in that position by means of the notch a on the gravity-catch B; but at Fig. IV the bolt J is represented as being through the body of the car.

thrown back into the case E L, and held in that position by the shoulder or catch 1), catching into the ring part F V. The catch B is pivoted, so that its lower end lies to the left of the vertical line, whereby the weight of the catch always prevents the bolt J from changing its position, and at the same time the lock cannot be tampered with from the outside of the car, except by cutting away the post or cutting A hole, K, is formed through the plate E, opposite to the ring F V; where the latter is in position, as when the door G is locked, to connect the plate and bolt by a seal, if desired. At H the door is represented as broken away, that the position of the bolt J in the door-catch I may be seen. The catch I is formed to fit the contour of the end of the bolt J; but any other of the ordinary forms of catches will serve the purpose-as, for instance, a flat plate attached to the side of the door and provided with a slot for the bolt to engage. In the present construction I find it convenient to cast the plates E and L separate, and secure them together by rivets a; as. It is proper to state that it is necessary that the lower corner of the ring F V should have a seat formed in the wood, that it may not pass below the position shown at Figs. I and II. To form a suitable guide and support for the catch B, the ordinary recessed strap plate, 0, is employed at a short distance below the pivot D. The position of the bolt J is to be changed by swinging the catch B and elevating or depressing the ring F V.

I claim as new- The gravity-catch B, provided with the notch a and catch b, and pivoted, as specified, in combination with the bolt J ,which is formed in one piece with the loop F V, for locking the bolt in the door, and looking it when out of the door, as specified and shown.
